3 Claims. (crass-1'1) This invention relates to a pump and it is one object of the invention to provide a pump which is particularly adapted for pumping water from a stream into a tank or equivalent reservoir from which the water is to'be conducted through pipes to farm buildings or other places where it is to be used.

, 1 Another object of the invention is to provide a pump wherein water is delivered from the stream into a container which is mounted over a pump cylinder and connected with the piston so that when the container is filled and released it may move downwardly and act as a unit for thrusting the piston downwardly in the cylinder. Another object of the invention is to provide mit water to flow from the container after the piston has made a down stroke, the empty container being then pulled upwardly to its raised position by a counterweight where it is refilled. Another object of the invention is to provide a latch for releasably holding the container in its raised position,the latch being moved to a releasing position by a weight consisting of a receptacle filled with water overflowing from the main container and the receptacle having anoutletat its bottom' normally closed by a valve carried by a pull line so that after the receptacle a releasing position, the receptacle will be emptied has moved downwardly and shifted the latch to l and the latch returned to its operative position a for securing the container in its raised position.

Another object of the invention is to provide a pump structure in which the various operating This improved pump structure includes a pump cylinder I which extends vertically in a casing 2 and has its upper end connected with a pipe section-thy a coupling 4 and its lower end connected fragmentary view of the latch for with a pipe 5 by'a coupling 6. The. pipe 6 and the casing 2 may beof any length and extend into a sump or the like .to which water is delivered from, a river. An upwardly opening check valve! is mounted between the lower end of the cylinder land the coupling 6 so that,:as the piston 8 moves upwardly, water may be drawn into the cylinder and the valve closedduring downward movement of the piston for forcing the water through the discharge ,pipe 9. The discharge pipe leads from the pump to a storage tank or other suitable reservoir and has inter? posed therein a valve 1.; This valve ID has a casing or housing ll carrying a head [2 at its upper end for connecting it with the pipe 8. The section 13 1of the pipe extends upwardly into the valve housing through the bottom thereof and upon its upper endrests a valve ball l4 formed of hard rubber or other. suitable material. A cross bar l5 serves to limit upwardly movement of the valve ball so that as the piston moves downwardly in a power stroke, water may be forced through the discharge pipe without interference by the ball. During the upstroke of the piston, theball seats itself upon the upper end of the pipe sectionor nipple I3 and holds water in the discharge pipe above the valve in during movement of. Water into the pump cylinder through the valvei'l. a I l The upper end of the pipe section 3 communicates with a sump l6 formed in concrete H and having an outlet opening [8 at one side. The a concrete is also formed with a recess 0r pocket [9 having an out1et'20 at one side, this pocket being of less dimensions than the sump l6 and spaced laterally therefrom. Posts or standards 2i rise from the concrete base I! and are arranged as shown in Fig. 3, so that sleeves 22 at corners of a rectangular tank or receptacle 23 may fit about the posts and slidably mount the tank for. vertical movement. At its bottom, the tank is formed with an outlet opening 24 controlled by a valve 25 carrying a gasket 28 which seats against the bottom of the tank and closes the opening 24. The body portion of the valve is of such size that it has sufficient weight to quickly carry it downwardly toward closed position and its lower end is reduced to form a projection or. nose 21 which fits tightly in the opening. of the gasket 26 and frictionally holds the gasket in engagement with the metal valve. A bridge or yoke 28 is mounted against the under face of the bottom of the tank in crossing relation to the ,outlet opening 24. and to this bridge is attached the upper end of the piston rod 29. Referring to Fig. 1, it will be seen that when the tank is in its raised position the piston will be at the top of the cylinder and that, as the tank moves downwardly, the piston will be thrust downwardly restsv on the base I! when the tank is in raised position. This bucket is filled with water until the weight is sufiicient to draw the empty tank upwardly to raised position, and the capacity of the tank is such that when it is filled, the weight will overcome the weight of the filled bucket and permit the tank to slide downwardly. The pulleys are carried by a supporting beam 31 which also carries a screw eye 38 to which the upper end of a'looped rope 39 is attached. The lower end of the rope is attached to the valve '25 and it is of such length that when the tank moves downwardly and reaches a point close to the base, the rope will be extended its iull length and the valve moved to open position so that the Water may drain from the tank into the sump, from which it flows through the outlet 18. The piston is forced downardly in a power strike as the tank moves downwardly and immediately the tank is emptied, the weight of the filled bucket returns it to its raised position.

- A latch or keeper d'ii'stracldles the beam 31 where it is vpivotally mounted by -a bearing clip 4|. Lower ends of the arms of the keeper are brought together and formed with hearings or eyes to receive the shaft 4'3 carrying a roller 44 for engaging under the bill 32 and support the tank in its-raised position. A spring 45 extends longitudinally of the beam 31 at'one side thereof and has its inner end engaged with a shackle 46 clamped about one arm .of the latch, a'nd'the outer end of the .spring is engaged with a hooked rod which passes througha bracket 48 and carries a nut fliliso that byturning the nut, tension of :the spring may be controlled. This spring yieldably holds the keeper in its operative position but permits it to be swung to inoperative position, in which position the roller moves from under the bill and allows the container to move downwardly. I Y

The keeper is only :to bemoved to a-releasing position when the :tank isfilled and, in order to do so, the .tank has its upperend formedwith a spout 51 through whichwater may overflow from the tank and into ;a bucket 51. This bucket is carried by a rope '52 which is trained about a pulley 5.3 carried by .a bar 5.4 and-its upper end portion extended horizontallyandconnected with a shackle 55 clamped about the adjacent arm of the keeper. Wherr the bucket'5-i is-empty,-the spring will hold the :rollerunder the :bill 32 and prevent downward movement of the tank, but when the bucket is filled with a predetermined quantity of water, its weight will :move the'keepe-r to its releasing position and allow .theta'nk :to

the pocket IS. The speed at which water flows from the tank and the bucket is such that the tank makes a. down stroke and then returns to its raised position before the keeper moves to its operative position. Therefore, when the keeper returns to its operative position, its roller may engage under the lip 32 and hold the tank raised until the tank is again filled and sufficient water has flowed through the spout 50 to fill the bucket and cause release of the tank. It will thus be seen that the elements oithe pump will operate in timed relation to each other and the piston reciprocated vertically to draw water into the cylinder I and then force it out through the discharge pipe. The tank is filled with Water flowing through ,a feed pipe which leads from the river and terminates over the tank.
